God Bless You. My little sister has learned how to flash. Unfortunately, she doesn't know how to control it, and it's all wet and messy, so as her brother, I honestly can't stand it. She makes mean comments like, "You're not letting it grow big, are you?♪" and flashes her panties (and sometimes her genitals) at me, teasing me with lewd words... I counter by sliding her panties aside and inserting myself into her, with her eagerly accepting it with a nervous face! Of course, she repeatedly calls me "Big Brother♪" in her debut as a little sister and in her school uniform, playingfully enticing me with all her might!
